filling.
If during the filling process, the portable oxygen unit
is disengaged with the vent valve lever open,
pressure may be reduced within the portable oxygen
unit and cause a delay in its function. It may require
as much as 60 minutes to restore adequate pressure
for accurate oxygen flow. Additionally, the portable
oxygen unit will not pulse properly when improper
filling lowers normal operating pressures.
The portable oxygen unit is most likely to hiss after
filling or with a change in the position of the
portable oxygen unit or when the flow control valve
is at a low setting. Hissing can last for approximately
ten minutes after filling. Hissing can be evidence of a
leak or normally occur to correct the internal
operating pressure of the unit.
